Sungevity has announced a joint venture with Nickel Energy, appropriately enough called Sungevity Australia and pioneering a program being called "RoofJuice". It's the first pay-as-you-go solar power program in Australia.

Sungevity says:

The average cost of a five-kilowatt system (the average system size in Australia) is 12,000 Australian dollars ($12,400). Now, with the introduction of Sungevity Australia’s “RoofJuice” option, homeowners can purchase solar-generated electricity with no upfront cost, giving them instant savings on their utility bills. Sungevity Australia’s “RoofJuice” option will be available starting in late May 2012 and will incorporate the company’s brand assets and proprietary software tools, including the company’s remote solar design services.
